Authenticated control sequences to initialize sensors over a multi-target interface bus

A system comprising:

• a plurality of sensors;
• an interface bus coupled to the plurality of sensors and configured to operate with a multi-target interface protocol;
• and
• a processor coupled to the interface bus, the processor to execute instructions to perform operations comprising:
• creating a broadcast sensor object;
• creating a broadcast client object using the broadcast sensor object;
• broadcasting initialization data, according to the multi-target interface protocol and using the broadcast client object, to the plurality of sensors;
• generating, from the initialization data, using at least one cryptographic function, an authentication tag for each sensor of the plurality of sensors, wherein each authentication tag is specific to a corresponding sensor of the plurality of sensors;
• and
• unicasting, according to the multi-target interface protocol, each authentication tag to the corresponding sensor of the plurality of sensors.

A non-transitory computer-readable storage medium storing instructions which, when executed by a processor coupled to an interface bus, cause the processor to perform operations comprising:

• creating a broadcast sensor object;
• creating a broadcast client object using the broadcast sensor object;
• broadcasting initialization data, according to a multi-target interface protocol over the interface bus and using the broadcast client object, to a plurality of sensors;
• generating, from the initialization data, using at least one cryptographic function, an authentication tag for each sensor of the plurality of sensors, wherein each authentication tag is specific to a corresponding sensor of the plurality of sensors;
• and
• unicasting, according to the multi-target interface protocol, each authentication tag to the corresponding sensor of the plurality of sensors.
